With one Grammy, three Tony’s and every other possible award you can win for Broadway under his belt, “In The Heights” creator Lin-Manuel Miranda can both literally and figuratively write his own destiny.

Tonight, Lin-Manuel lets someone else pen the words as he guest-stars on “Modern Family” as a sketchy obedience trainer with a get rich quick scheme that Gloria adores and Jay abhors. I caught up with the innovator to talk about his real life puppy love, when you might be able to see his “Bring It On Musical” and what show will (hopefully) bring him back to Broadway!

PopWrap: How did this “Modern Family” gig come about?

Lin-Manuel Miranda: It was all very quick. I had met the producers the summer before when I was doing “In The Heights” in Los Angeles — they called me and I flew out. Simple as that.

PW: And this intense look your character is sporting, was that the plan from day one?

Lin-Manuel: [laughs] No. I showed up on set, and in any other context this would be great, but they said, “you look too nice and too winning.” So on the lunch break they mussed me up, gave me those mullet extensions and there you go. Suddenly an amazing hairstyle was born.

PW: What can you tell us about your character, Guillermo?

Lin-Manuel: Basically he has an idea for a dog business that he hopes Jay will invest in. Gloria kind of adopts human strays — she’s very kind hearted & has trouble saying no to people — so the next thing you know, Jay’s listening to my pitch because of her. It’s fun because the character is this really weird loser who has no business being in that house. But it’s a fantastic way to explore Jay & Gloria’s relationship.

PW: Are you a dog person in real life?

Lin-Manuel: I am. My wife is a cat person and I’m a dog person, so we cancel each other out and have nothing. But I grew up with dogs and love dogs. That was the other thing, since I was playing an animal trainer, I had to learn to “speak dog” on-set so it looked like I know what I was doing. My dog was a total pro.

PW: Big dog fan here as well, sometimes I even ‘dog’le — you ever do that.

Lin-Manuel: Yea …. no [laughs]. However I grew up across from Inwood Hill Park, which is the non-curb your dog capital of the world. I used to call the street across from me S***Pipe Alley. It was inspired by a kids show that Mario Cantone used to host called “Steam Pipe Alley.” It was the weirdest show. An audience full of screaming kids and he’d do Judy Garland jokes. It all went over my head. It was pretty amazing, I bet you can find it on YouTube [ed note: YOU CAN!]

PW: You’re also working on “Bring It On: The Musical,” how’s that going?

Lin-Manuel: It’s coming along great. We did our first production of it in Atlanta this winter and they ate it up. We know there’s still work to do, but the fact it was so enthusiastically received – even in that state — makes me really excited. We’re opening in LA in November, so that’s the next hurdle.

PW: Is your version a literal adaptation of the film or does it just use the plot as a jumping off point?

Lin-Manuel: The second one – Jeff Whitty had an amazing idea for an original story that’s set in the world of competitive cheerleading. It’s more like “All About Eve” than “Bring It On.” But there are elements of the original movie – two competing teams and the killer one-liners that only Jeff Whitty can write.

PW: There was also talk of an “In The Heights” movie last year, but then the studio backed out — where are you with that now?

Lin-Manuel: I definitely think an “In The Heights” movie will happen, just not with Universal. The day that news came out, we got seven other offers, so we’re sifting through that stuff now. There’s still a lot of enthusiasm out there for it, we’re just trying to figure out the best road to take it down.

PW: Any plans for another wholly original Lin-Manuel musical?

Lin-Manuel: Actually, I’m going off this summer with Tommy Kail and working on something we’ll write from scratch. So that’s an exciting part of my summer. When you work in the theater, you have to work on three things concurrently because you never know what’s going to happen, so I’m also working on a new show with my “In The Heights” collaborator Quiara [Alegria Hudes], so we’re just getting started on that too. It’s all really exciting.
